158 PIG-FOOTED BANDICOOT known, burrows in the soil, whence it extracts grubs; it is also a grass-feeder, and it is said that its likeness to a Babbit in appearance is strengthened by its similarity in flavour! Perameles is a genus consisting of twelve species, which are found in Tasmania, Australia, and Hew Guinea. Like the last genus, from which it does not widely differ in other points, Perameles consists of species which combine insectivorous and vegetarian habits. One species is said to become in captivity an expert in catching mice. The pouch opens backwards, and there are six or eight mammae. The last genus of this family is Choeropus, containing but one species, Cfa. castanotis. It is confined to the Australian con- FIG. 87.—Pig-footed Bandicoot. Choeropus castanotis. x £. tiaent. It is to be distinguished from the last two by the fact that there are only two functional digits, the second and third, in the fore-limb; the fourth is rudimentary; the other two are absent. It burrows, and is omnivorous like its allies. The two metacarpals that are developed are very long and closely apposed; they have hence a remarkably pig-like aspect, and* justify its name. The pouch opens backwards, and there are eight mammae. Fam. 4.
